A student-led project comparing satellite images of the Arctic has discovered that a small Russian island has recently vanished after "completely melting" away.

The cryovolcanic "centaur" comet 29P/Schwassmann-Wachmann has erupted four times in less than 48 hours, becoming unusually bright in the process. It is the most powerful outburst from the city-size oddball in more than three years.

A recent satellite image captured the reemergence of a unique, UFO-like cloud, known as the "Taieri Pet," which appears above New Zealand's South Island when conditions are just right.

A new video shows how Earth's magnetic field weakened and warped before temporarily flipping during a recent "polar reversal event."

Newfound comet C/2024 S1 will light up Earth's skies in late October before a super close slingshot around the sun.

Newly released images of Mars reveal a "smiley" salt deposit on the Red Planet's surface. A related study suggests that similar deposits, which were left behind from ancient lakes, may be a good place to look for signs of former life on Mars.

New studies, which utilized AI to monitor the effects of climate change on Earth's spin, have shown that our days are getting increasingly longer and that our planet will get more wobbly in the future. These changes could have major implications for humanity's future.

Some experts believe that the solar system's hypothetical ninth planet could be just a few years away from being discovered. If this is the case, how long would it take for humans to send probes to the elusive world?

Astronomers have been scouring the outer solar system for signs of a hypothetical ninth planet for almost a decade, without success. However, we may finally be on the cusp of finding it, experts say.

Alaska's melting permafrost is dumping toxic metals into the state's rivers, turning them bright orange and making the water highly acidic. The contaminated rivers are so vibrant they can be seen from space, and the problem is likely to get much worse in the future.

A tiny, previously undisclosed lunar rover has been spotted strapped to the side of China's moon-bound Chang'e 6 lander in newly released pre-launch photos. The true purpose of the rover, which is scheduled to land on the moon's far side, remains a mystery.

Several media outlets have incorrectly claimed that explosive solar flares were spotted during the April 8 total solar eclipse. But there were no flares during totality, so what did people see?

A new study warns that 5,000 meteorites could be sinking beneath Antarctica's icy surface every year as a result of climate change, depriving scientists of vital information about our solar system.

New images show a glowing "dashed" line in the night sky above Arizona after part of a SpaceX Falcon 9 rocket fell back to Earth following a double-header launch.

Earlier this month, a sudden atmospheric warming event caused the Arctic's polar vortex to reverse its trajectory. The swirling ring of cold air is now spinning in the wrong direction, which has triggered a record-breaking "ozone spike" and could impact global weather patterns.

A reanalysis of 50-year-old Apollo mission data long abandoned by NASA has revealed 22,000 previously unrecognized moonquakes, almost tripling the known number of seismic lunar events.

New, specially edited photos show a previously unseen swirl of light surrounding the city-size comet 12P/Pons-Brooks, which is currently racing toward the sun and will later zoom past Earth.

A massive column of sulfur dioxide pumped out by the erupting volcano on Iceland's Reykjanes Peninsula is traveling across northern Europe. Scientists are concerned it could impact the ozone layer.

A large swirl of white light that temporarily outshone vibrant auroras in the Arctic last week was triggered by the death throes of a SpaceX rocket that deployed more than 50 satellites into space.

A gigantic plasma eruption from the sun's hidden far side recently launched a sizable coronal mass ejection that slammed into Mercury, potentially triggering invisible X-ray auroras around the planet's rocky surface.

The proposed nuclear reactor, which could be transported and assembled without human assistance, would provide energy to a lunar base that Russia and China have agreed to build together.

Comet 12P/Pons-Brooks is currently sailing past the Andromeda Galaxy in the night sky as it races toward Earth, and you can watch it live today.

A NASA satellite recently spotted a series of bizarre "fallstreak holes" in clouds above Florida. The circular cloud gaps have been previously (and incorrectly) linked to paranormal phenomena.

Researchers found and mapped four seamounts in the deep sea off the coast of Peru and Chile. The tallest of these new peaks rises around 1.5 miles above the seafloor.

A recent solar flare unleashed a massive plasma plume from the sun's south pole, where these stellar eruptions rarely happen. The unusual phenomenon is a sign of the impending solar maximum.
